Description

The present invention relates to a light-transmissive building material and furniture furniture.

Conventionally, the wood board which sliced the wood thinly is widely used. Many of them are used for cosmetics to show wooden plywood as solid wood. In addition, there is a material in which a backing plate backing sheet is sandwiched and bonded between two sheet glasses via an adhesive film, and this is also developed and used for surface decoration of furniture furniture (for example, see Patent Document 1). . On the other hand, products that use the thinness of the wood board to transmit light to the wood board as a shade of a lighting fixture and enjoy the grain and color of natural wood are also manufactured and sold. As the board for lighting fixtures, in order to eliminate the weakness such as cracking and tearing and to give strength, Japanese paper, non-woven fabric and the like are bonded to the board and backed.
JP-A-6-182933

In the case of a single sheet of wood board that has been used for lighting fixtures in the past, it is possible to add a design such as a pattern or gradation intended by the producer simply by floating the wood grain when viewed through illumination or natural light. Although not possible, the natural wood veneer piece laminated sheet and the material using the same according to claim 1 of the present invention make it possible to add the design intended by the producer.

Conventional laminate, laminate laminated sheet or double-sided laminate sheet sandwiched between sheet glass (Patent Document 1) is mainly provided for the surface decoration of furniture furniture, The natural wood veneer board laminated sheet of the present invention and the materials 1, 5, 7, and 9 using the same are architecture, fittings, partitions, furniture, lighting equipment, etc. that take into account the aesthetics and shading design when light is transmitted. Provided as a light transmissive material that can be used for

A conventional natural wood veneer is a single piece of wood sliced, and there is a limit to the size that can be produced depending on the size of the tree and the size of the machine, but the natural wood according to claim 1 of the present invention. The board laminate sheet eliminates the limit of the size that can be produced.

When light is transmitted through the veneer and used for lighting equipment, etc., the conventional veneer can easily be cracked or torn by the grain, and cannot be used without reinforcing the backing material such as Japanese paper or nonwoven fabric. The natural wood veneer small piece laminated sheet according to claim 1 of the invention is less prone to cracking and tearing, and can be used without a backing material for reinforcement.

A light-transmitting natural wood veneer piece laminated sheet 3 is produced by adhering natural wood veneer pieces in a random manner or in a pattern intended by the producer so that the fiber directions of the wood overlap in various directions.

A natural wood veneer small piece laminate composite sheet is produced by adhering a sheet material having high translucency to one or both sides of the natural wood veneer piece small laminate sheet.

A light-transmitting material obtained by sandwiching and adhering the natural wood veneer piece laminated sheet according to claim 1 or the natural wood veneer piece laminated composite sheet according to claim 2 through an adhesive layer between two transparent or translucent materials. Material 1 is produced.

The light-transmitting material 5 is produced by sandwiching the sheet according to claim 1 or 2 between two transparent or translucent materials, sealing the periphery, and sealing.

A light-transmitting material 7 obtained by adhering the natural wood veneer board piece laminated sheet according to claim 1 or the natural wood veneer piece laminated composite sheet according to claim 2 to one or both sides of a transparent or translucent material via an adhesive layer, 9 is produced.

The natural wood veneer board small piece laminated sheet 3 according to claim 1 of the present invention and a material using the same are made by bonding together when viewed through light or natural light while taking advantage of the texture and color of the natural wood. It is a material that has a unique texture such as shading and aesthetics, and can add original designs such as patterns and gradations intended by the producer.

The raw materials 1, 5, 7, and 9 using the natural wood veneer piece laminated sheet or the natural wood veneer piece laminated composite sheet of the present invention are not for surface makeup, and have a unique aesthetic appearance and shadow when transmitting light. By selecting and using a transparent or translucent material 2 according to the place and area of use, it can be given strength and durability suitable for the place of use. It is a light transmissive material with excellent design that can be used for joinery, partitions, furniture, lighting fixtures, etc.

Since the light-transmitting natural wood veneer piece laminated sheet 3 according to claim 1 of the present invention is produced by laminating several pieces of veneer pieces, it is possible to eliminate the limit on the manufacturable size. Even when used as the material 1 and the material 5 for the outer wall of a building, a large area can be produced seamlessly.

Since the natural wood veneer small piece laminate sheet according to claim 1 of the present invention is a laminate obtained by cutting a veneer plate having a thickness smaller than that of a conventional veneer into small pieces and laminating and laminating wood fibers in various directions. Compared to a single sheet board, the thickness is much higher and the strength is much higher. It can be used for shades of lighting fixtures without a backing material, and is easy to handle when used for materials 1, 5, 7, and 9.

The thickness of the natural wood veneer used in the present invention is preferably about 0.05 mm to 0.3 mm. This is made by thinly slicing wood having a width of about 3 cm to 15 cm, a length of about 1 m to 2 m, and a thickness of 1 cm or more. A thin and uniform board can be obtained by using a mechanical super-finished canna for slicing. The tree species is not particularly limited, but it is preferable that the grain is fine as it is thin and easy to handle. The grain direction is desirable in consideration of the shrinkage at the time of bonding, but is not limited thereto. The width, length, and shape when cutting into small pieces are adjusted according to the place used, the area, and the design intended by the creator and designer.

When sticking the small pieces of adhesive board, the adhesive can be peeled off after curing, and a light-transmitting synthetic resin sheet (thickness of about 0.5 mm to 2 mm) that can confirm shadows, light transmission conditions, designs, etc. during production Acrylic sheet, PET resin sheet, etc.) are used for the table.

The adhesive is thinly and evenly applied to one side of the board made as described above, cut into lengths, and then randomly pasted so that the fiber directions of the trees overlap in various ways.
Or put it on the design intended by the producer / designer. The intended design is, for example, a method of overlapping small pieces of wood board in two kinds of constant angle directions, such as netting knitting found on the ceiling of a tea room, a method of overlapping according to a certain law or angle, and darkness when transmitting light ( There are a method of giving a gradation so that it gradually becomes lighter (lighter) from a dark place, and a method of cutting and stacking the small pieces of the board itself into leaves, petals, circles, and the like.

The number of the overlapping small pieces of the plate is limited to one sheet at a small number and up to about six sheets at a large number. In addition, it is possible to create a holed hole without sticking even one piece, and if it is scattered many times and used as a partition or window part, an effect like a moth that can see the outside from the near side and the inside from the far side can be obtained. It is done.

When stacking the small pieces of the board, when sandwiching between the transparent or semi-transparent materials shown in the material 1 and the material 5, they are stacked while being in close contact so that air does not enter. When adding an intended design, work while allowing light to pass through. The adhesive used here must be one that becomes transparent or nearly transparent when dried (for example, a vinyl acetate resin emulsion adhesive). In addition, it must be resistant to heat and light. When the adhesive is cured and then peeled off from the base of the light-transmitting synthetic resin sheet, the natural wood veneer small piece laminated sheet according to claim 1 is obtained.

Adhering a highly transparent sheet-like material (Japanese paper non-woven fabric, adhesive resin sheet that does not affect the light transmission of the board) to one or both sides of the natural wood board board laminated sheet 3 Then, the natural wood veneer piece laminated composite sheet of claim 2 is obtained. The adhesion of the sheet-like material has the purposes of reinforcing and reducing the shrinkage of the laminated sheet-piece laminated sheet, and enhancing the adhesion with other materials.

FIG. 1 shows a light-transmitting material 1 in which a natural wood veneer piece laminated sheet 3 obtained in this way is sandwiched between two transparent or translucent materials 2 via an adhesive layer 4. The same applies to the case where the natural wood veneer board piece laminated sheet 3 is used as a natural wood veneer piece laminated sheet. The transparent or translucent material 2 used at this time is glass, acrylic resin, polycarbonate, etc., and the material, thickness, strength depending on the place (floor, wall, ceiling, joinery, furniture, etc.), area, use, etc. Select in consideration of such functions. (For example, when it is used for an interior partition wall of 900 mm × 1800 mm, the thickness when plate glass is selected is about 3 mm to 4 mm). For the adhesive layer 4, an adhesive, an adhesive resin sheet, a thermoplastic resin sheet, or the like is used. However, any transparent material that does not affect the light transmission of the board is used. After the natural wood veneer piece laminated sheet is sandwiched between the two light-transmitting materials 2 via the adhesive layer 4 in this way, when it is bonded by thermocompression bonding by a method conventionally used for producing laminated glass, the light shown in FIG. A transparent material 1 is obtained. The same applies to the case where the natural wood veneer board piece laminated sheet 3 is used as a natural wood veneer piece laminated sheet. When the light-transmitting material 1 is a conventional laminated glass, it has an anti-crime, safety and UV-cutting function by increasing the interlayer film of the laminated glass and sandwiching it between them. A new light-transmitting building material having design properties can be obtained.

FIG. 2 shows a light-transmitting material 5 according to claim 4, which is manufactured by sandwiching a natural wood veneer piece laminate sheet 3 between transparent or translucent materials 2 and sealing and sealing the periphery. The light-transmitting material 2 used here is glass, acrylic resin, polycarbonate, etc., and the necessary functions (strength, water resistance, contamination resistance, weather resistance, etc.) can be selected by selecting the material and thickness depending on the place of use as in the case of the material 1. Etc.) can be added. In this case, it can be manufactured without an adhesive layer. The same applies to the case where the natural wood veneer board piece laminated sheet 3 is used as a natural wood veneer piece laminated sheet.

FIG. 3 shows a light produced by bonding a natural wood veneer small piece laminated sheet 3 via an adhesive layer and a highly transparent sheet material 8 on both sides of a transparent or translucent material 2 (glass, acrylic resin, polycarbonate, etc.). This is a transparent material 7. The sheet material 8 having high translucency is preferably a thin one that has high translucency among Japanese paper, non-woven fabric, cloth and the like and does not affect the light transmissivity of the natural wood veneer piece laminated sheet. In addition, when the natural wood veneer board piece laminated sheet 3 is a natural wood veneer piece laminated composite sheet, it can be produced in the same manner.

4 is transparent or translucent material 2 (glass, acrylic resin, polycarbonate, etc.) on one side, adhesive layer and highly translucent sheet material 8 (Japanese paper, non-woven fabric, cloth, etc.) The thin wood sheet laminated sheet 3 is manufactured by bonding through a thin sheet that does not affect the light transmittance of the wood board sheet. In addition, when the natural wood veneer board piece laminated sheet 3 is a natural wood veneer piece laminated composite sheet, it can be produced in the same manner.

In addition, since the raw material of Claim 1 and Claim 4 of this invention will be in the state in which the natural wood is exposed as it is on the surface, it can enjoy the fragrance and texture of wood. For example, when hinoki is used, deodorizing and bactericidal effects of hinoki oil contained in cypress can be obtained.
